Abstract

Most of propellants that is used widely in the world release toxic gases such as methane gas and carbon dioxide during combustion which are noxious to the environment. This study established a synthetic process of a high nitrogen containing derivative of triazole, 4,5-bis(azidomethyl)-methyl-1,2,3-triazole (DAMTR), which can be applied as energetic plasticizer to environmental concerns. Also, the compound was characterized by NMR, IR spectroscopy, and physical properties such as glass transition temperature, melting point, decomposition temperature, density, impact sensitivity, viscosity and volatility were measured. In addition, the heats of formation (${\Delta}H_f$) and detonation properties (pressure and velocity) of DAMTR were calculated using Gaussian 09 and EXPLO5 programs.

세계적으로 사용 중인 대부분의 추진물질들은 연소 시 메탄가스, 이산화탄소 등의 환경유해 물질을 다량 발생시킨다. 본 연구에서는 이러한 문제를 개선하기 위해 에너지 가소제로 사용 가능한 고질소 화합물인 트리아졸 계열의 4,5-bis(azidomethyl)-methyl-1,2,3-triazole(DAMTR)의 합성공정을 확립하였다. 또한, 분광분석(NMR, IR)을 통해 DAMTR의 구조를 분석하였고, 유리전이온도, 녹는점, 분해온도, 밀도, 점도, 충격감도, 점도, 휘발성 등의 물리적 특성을 측정하였다. 그리고 Gaussian 09와 EXPLO5를 이용하여 생성열과 폭발 특성(폭압, 폭속) 등을 계산하였다.
